OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 460,902, dated October6, 1891. Application filed April 13, 1889. Serial No. 307.120. (N0model.)

To all whom it may concern:

Be it known that I, RUnoLE WINKLER, a citizen of the United States,residing at Detroit, county of IVayne, State of Michigan, have inventeda certain new and useful Improvement in Oil-Burners; and I declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to a new and useful improvement in an oil-burner;and it consists of the devices and appliances and their combinations, asmore fully hereinafter described, and set forth in the claims, and moreparticularly illustrated in the accompanying drawings, in which Figure 1is a horizontal section of a portion of a combustion chamber or furnace.Fig. 2 is ahorizontal section of the burner, and Fig. 3 is a verticalsection of the burner.

I carry out my invention as follows:

A represents the combustion-chamber of a B denotes the side wallsthereof, and B the front of the furnace.

My improved burner consists, essentially, of an inclosing case 0,forming a vaporizingchamber C, said case terminating at its forward endin a nozzle C preferably made flaring, so that the mouth of the nozzlewill be elongated. The nozzle is also preferably cut away at thesidesas, for instance, at c 0'- to allow the freer distribution of thevaporized oil and to permit its being discharged broadly into thecombustion-chamber.

D represents a steam or blast pipe entering the case C, and preferablyextending therein, so as to penetrate the nozzle C the steampipe itselfterminating in an expanded or flaring nozzle (Z. This nozzle is also contracted vertically, as shown in Fig. 3.

E and E are air-pipes communicating with the interior of the case 0, andsuitably extended therein, as shown, so as to throw the inflowing airwell toward the nozzle of the burner.

I is a supply-pipe to feed the oil to the nozzle of the burner, the saidsupply-pipe entering the top of the nozzle 0 as shown, and

preferably terminating in said nozzle with a crescent-shaped discharge-nozzlef, the mouth of which is suitably contracted to governthe discharge of the oil therefrom in a thin crescent-shaped sheet anddirectly forward of the nozzle of the steani-jet through the pipe D.

It is to be particularly observed that the openings in the terminal endsof the oil-pipe and steam-pipe, respectively, are of analogous form andthat they are elongated in the same direction, the opening in theoil-pipe being in advance of and slightly above the opening in thesteam-pipe. The arrangement is therefore such that the oil will feedfrom the top, being emitted into the vaporizing-chamber in a thinelongated sheet directly in front of the blast issuing from the pipe D,also in a thin elongated blast under pressure, at substantially rightangles to the sheet of oil as it is 7c being emitted from the oil-pipe,whereby the oil is instantly sprayed. This construction and arrangementof the terminals of the oilpipe and blast-pipe proves to be of greatefliciency. The case 0 acts as a shield to pre- Vent the sprayed oilfrom striking the bottom of the boiler.

The oil-supply pipe I prefer to lead through a superheater of anydesired construction,- (shown in outline at G,) and having a steam- 8oheating pipe II, leading thereinto.

The operation of the device is as follows: The steam-jet through thepipe D, acting as an injector, creates a draft of air through the pipesE E toward the nozzle O of the burner, while at the same time theexpanded jet of steam through the nozzle (Z, immediately in the rear ofthe crescent-shaped nozzle of the oil-pipe, immediately penetrates theoil as it is discharged through the nozzle f, and the coininingled air,oil, and steam is discharged broadcast through the flaring mouth of thenozzle C in the form of vapor into the combust-ion-chamber and readilyconsumed. The oil-pipe may be provided with a regulatingvalve f. Anadditional valve f may be provided to regulate the flow of oil throughthe super-heater.

The device is obviously simple, not liable to get out of order, easilyoperated, and very I00 efficient. The elongation of the openings in theterminals of the oil and steam pipes is in the same direction and shouldbe made on the arc of a circle, so that the steam emitted radially fromthe one opening will vaporize and spread the oil in radial lineslaterally as well as straightforward, the radial or lateraldissemination of the vaporized oil being a matter of much importance, asthereby much better combustion and every way more satisfactory resultsare attained.

I prefer to slightly depress theupper edge of the nozzle 0 so as toforce the vapor more effectually upon the flame, and more especially toprevent it from striking the boiler and coating it with carbon. By thusconstructing the nozzle the vapor in combustion is kept down and awayfrom the boiler, so as to be wholly consumed, leaving the boiler freeand clean from any deposit thereupon. So, also, as shown, I prefer totaper the case C toward the forward end or nozzle C in order to moreeffectually concentrate the air and commingle it more efficiently withthe steam and vaporized oil.

WVhat Lclaini as my invention is- 1. In an oil-burner,the combination ofan oilpipe F, having a vertically-extended extremity terminating in anarrow elongated opening curved in the arc of a circle in its lower endfor the emission of oil therefrom in a vertical thin elongated sheet,and a blast-pipe D, extending at an angle to the oil-pipe andterminating at its forward end in a narrow elongated opening curved inthe arc of a circle for the emission of a jet or blast therethrough in athin elongated sheet to spray the oil emitted from the oil-pipe, saidopenings being each elongated in the same direction and the 7 opening ofthe oil-pipe arranged in advance of the opening in the blast-pipe inproximity thereto, substantially as described.

2. In an oil-burner, the combination, with a case, of an oil-pipe F, ledinto the top of said case and terminating in a narrow elongated openingcurved in the arc of a circle in its lower end for the emission of oiltherefrom in the vertical thin elongated sheet, and a blast-pipe D,extending at an angle to the oilpipe and terminating in a narrowelongated opening at its forward end for the emission of a jet or'blasttherethrongh in a thin elongated sheet to spray the oil emitted from theoilpipe, said openings being each elongated in the same direction andthe opening of the oilpipe arranged in advance of the openings in theblast-pipe in proximity thereto, substantially as described.

3. Inan oil-burner, the combination, with a case forming avaporizingchamber and provided with a nozzle cut away at its sides andlaterally extended and vertically contracted and curved in the arc of acircle, of an oil-pipe led into the top of said nozzle and terminatingin a narrow elongated opening curved in the arc of a circle in its lowerend for the emission of oil therefrom in a vertical thin elongatedsheet, and a blast-pipe D, ex-

tending at an angle to the pipe, terminating in a narrow elongatedopening at its forward end for theemission of a jet or blasttherethroughin a thin elongated sheet to spray the oil emitted from the oil-pipe,said openings being each elongated in the same direction and the openingof the oil-pipe arranged in advance of the openings in the blast-pipe inproximity thereto, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
